BEFORE ATTEMPTING TO OPERATE THIS EQUIPMENT.

Death or serious injury could occur if this machine is used improperly.

SAFETY
MESSAGES

• Safety Instructions are proceeded by a graphic alert symbol
of DANGER, WARNING, or CAUTION.

GASOLINE/PROPANE POWERED EQUIPMENT

ous. It should only be dispensed in well ventilated
areas, and with a cool engine.

• Small gasoline engines produce high concentra­ tions of carbon monoxide (CO) example: a 5 HP 4

cycle engine operation in an enclosed 100,000
cu. ft. area with only one change of air per hour is capable of
providing deadly concenrations of CO in less than fi fteen min-
utes. Five changes of air in the same area will produce noxious
fumes in less than 30 minutes. Gasoline or propane powered
quipment should not be used in enclosed or partially enclosed
areas. Symptoms of CO poisoning include, headache,
nausea, weakness, dizziness, visual problems and loss of
conscious ness. If symptoms occur get into fresh air and
seek medical attention immediately.

ELECTRICAL POWERED EQUIPMENT

Extreme care must be taken when operating electric
models with water present: Ensure power cord is prop­erly grounded, is attached to a Ground-Fault-Interrupter
(GFI) outlet, and is undamaged.

• Check all electrical cables - be sure connections are tight and

cable is continuous and in good condition. Be sure cable is

correctly rated for both the operating current and voltage of

this equipment.

• Improper connection of the equipment-grounding conductor can

result in a risk of electric shock. Check with qualifi ed electri-
cian or service person if there is any doubt as to whether the
outlet is properly grounded. Adhere to all local codes and

ordinances.

• NOTE: In the event of a malfunction or breakdown, grounding

provides a path of least resistance for the electric current to

dissipate. The motor is equipped with a grounded plug and

must be connected to an outlet that is properly installed and

properly grounded. DO NOT modify the plug provided on the

motor. If the plug does not fi t the outlet have a qualifi ed elec-

trician install the proper receptacle.

• Switch motor OFF before disconnecting power.

Death or serious injury can result if this machine is used improperly.

Safety Guidelines

Maintain a safe operating distance from fl ammable materials. Sparks from the cutting-action of this saw can ignite fl am-
mable materials or vapors.

Operator must wear appropriate clothing and footwear. Do not wear loose clothing or jewelry that can get tangled
or caught in moving parts.

Eye and ear protection must be worn at all times when this machine is in use. During normal use, sound levels ex­ceed 85dBA. Use only ANSI approved safety glasses to help prevent eye injury. Everyday eyeglasses have only
impact resistant lenses; they are NOT safety glasses.

• Keep a safe operating distance from other personnel and never leave the machine running unattended.

• Maintain the machine in safe operating condition with all guards in place and secure, all mechanical fasteners
tight, all controls in working order and the saw confi gured for the job application.

• The SS-24 is designed to cut fl at, horizontal concrete or asphalt slabs using diamond saw blades.

• The SS-24 is to be operated by a single operator from a position at the rear of the saw.

• Avoid deck inserts, pipes, columns, openings, electrical outlets, or any objects protruding from slab surface.

• Inspect the blades carefully before installing. Do not use any questionable blade since serious personal injury
and/or damage to property can result.

• Never operate this saw while under the infl uence of drugs, alcohol or when taking medications that impair the
senses or reactions, or when excessively tired or under stress.

• Be sure all safety decals on the machine can be clearly read and understood. Replace damaged or missing
decals immediately.

• EDCO SP equipment are now equipped with an EVAP system to trap and dispose of fuel vapors before they can escape
into the atmosphere. This EVAP system contains a charcoal canister plumbed into the fuel system that transfers vapors
back to the engine to be burned. The fuel tank is sealed with a viton gasket in the cap. This cap is tethered to the tank.
Canister should be replaced every 10+ years.

Safety warnings and guidelines do not by themselves eliminate danger.

They are not given as substitutes for proper accident prevention and good judgement.

Before Starting the Engine:

• Read Rx for Concrete Saws before operating.

• Inspect machine before each use according to the Maintenance Schedule on page 15.

• Locate and be familiar with all engine and saw controls (Figure 2).

• Inspect the blades carefully before installing. Use the correct blade for the job. Check
rated RPM, diameter and size confi guration. Make sure blades are correctly mounted.

• For wet cutting, attach supply hose to Water Hook Up Valve (Figure 3).
NOTE: Do not fl ip Blade Saver switch to WET until after the engine has started.

• Adjust the handles for operator comfort and safe operation. Be sure to re-tighten
knobs once handles are positioned.

• Be sure cutting line is well defi ned.

• Move the saw into operating position.

Starting the Engine:

• Check to be sure blade is raised - not in contact with the slab surface and blade
guards are in place.

• Blade Saver switch (Figure 4) must be in the DRY position or engine will not start.
Note: The Blade Saver detects water pressure from the switch to the blade. If water
pressure drops below 2 1/2 gallons per minute, the switch will shut off the engine to
prevent damage to the machine and/or the blade.

• Check that the Emergency Stop (E-Stop) is in the UP position.

• Turn Engine Ignition key to START. After engine starts, leave Engine Ignition in the RUN position. Ignition position
on saw will vary depending on engine. (Review Figure 2)
NOTE: In cold weather, use the Choke to aid starting.

• If wet cutting, open Water Valve (or turn on Water Pump) then fl ip the Blade Saver switch to the WET position.
Check to be sure water fl ows freely to the blade. Water should be visible on the ground around the blade.

Figure 3

Figure 4

For blades marked DRY CUTTING, leave switch in the DRY position. While water is not required for
cooling, it may be used for controlling dust. For health reasons, it is strongly recommended that the
operator wear a respirator if cutting dry and water is not being used to control dust from the material

being removed. That dust may contain chemicals known to cause serious illnesses, including Silicosis
a fatal disease of the lungs. Check the chemical properties of the material to be removed and follow
all EPA/OSHA regulations.

Carbon Canister:

• The SS-24 is equipped with a charcoal canister to create a sealed fuel
system and re-route any vapors from the tank back to the airbox on the
engine for burning. This unit also has a tethered fuel cap with viton gasket
and evaporation resistant fuel lines. Life expectancy is estimated
at 10+ years.
